1 Claim.

This invention relates to a warp beam ho for yarn drying machines.

Application October 9, 1935, Serial No. 44,262

lder

drying machines.

Another feature of the present invention i sto provide a construction for one of the anti-friction bearings that allows the bearing to be moved axially and at the same time construct the a friction bearing in separable sections to fa nticilitate quick change and replacement of the warp beam.

Further objects of the invention are to provide a device of the character referred to tha tis drying machines and that is comparatively expensive to manufacture and install.

With the foregoing and. other objects in view the invention consists of a novel construction,

combination and arrangement of parts as be hereinafter more specifically described will and illustrated in the accompanying drawings, Wherein is disclosed an embodiment of the invention, but it is to be understood that changes, variations, and modifications may be resorted to w ithout departing from the spirit of the claim hereunto appended.

In the drawings wherein like reference characters indicate like parts throughout the several views:

Figure 11 is a top plan view of one of the sectional roller bearings.

Figure 12 is a detailed section taken substantially on the plane of line l2l2 of Figure 10.

Referring to the drawings in detail A and B indicate the two stands or side frames of a yarn drying machine. On the one stand A is supported a rotatable drive-shaft l5 and this shaft is driven through a suitable clutch control from the power mechanism of the yarn drying machine. is a roller bearing [6 in which an intermediate portion of the drive shaft I5 is journaled. Inwardly of the roller bearing l6 there is a collar I! secured to the inner portion of the drive shaft by means of a set screw I8. an end thrust bearing l9 against the roller bearing I6 to take up end thrust in the shaft. It will thus be seen that there is provided antifriction roller and thrust bearings for the drive shaft [5 which assembly materially reduces the friction on this drive shaft. The drive shaft l5 terminates inwardly of the stand A and on the free end is formed with a round socket 28 which merges at its inner end with a smooth round counterbore 2|. The free end of the shaft receives the end of one trunnion 23 of the warp beam.

The warp beam consists of a central drum 24 around which the yarn is wound between the heads 25 at the ends of the drum. Extending from one head 25 is the trunnion 23 heretofore described. From the other head 25 extends the trunnion 26 which is smooth and round. It is the aim of the present invention to provide an anti-friction bearing which will facilitate the quick and easy change and replacement of this warp beam, for when the warp beam is filled with yarn it is replaced by an empty one.

For driving the warp beam there is a hub 22a on a dog 22 detachably embracing the end of shaft I5. The hub is secured by a set screw 22b. There is an extension bolt 220- on the dog which engages with the head 25 on the warp beam and as the shaft l5 rotates the bolt drives the warp beam.

Bolted to the end face of the stand A This collar holds 2.

There is a hanger bar 21 bolted as at 28 to the other stand B of the yarn drying machine and extending rearwardly at right angles to the bar and integral therewith are a pair of spaced axle hangers 29, 39 which terminate in aligned sleeves 3|,782. The sleeves 3|, 32 form a support for the axially shiftable axle C and this axle extends through the sleeves. The confronting faces of the sleeves 3|, 32 are spaced toreceive the hub 33 of the hand wheel 34. The hub is formed with a central threaded opening 35 and Out-.'

wardly of the threaded opening the hub has a series of circumferentially spaced sockets 36.

The axle C is formed with threads 3'! which extend from the outer end to a point near the inner end. sleeves 35, 82 but are engaged by the threads in opening 35 in the hand wheel 84. It will thus be seen that by turning the hand wheel 64 in the proper direction the axle C will be shifted axially in the sleeves.

On the top of sleeve 3| is a horizontally bored lug 38. Slidable in the bored lug is a pin 39 having an operating handle 4| on one end thereof. The pin 39 is normally engaged with one of the openings 36 in the hub of the hand wheel under the tension of a coiled spring 42 which embraces an intermediate portion of the pin. One end of the coil spring 42 bears against the lug 38. The other end of the coil spring 42 bears on a collar 43 fixed to the pin 39. It will thus be seen that by pulling inwardly on handle 4| the pin is disengaged from the opening 86 in the hand wheel so that the hand wheel may be turned to move the axle C in or out. To prevent the axle C from rotating when the hand wheel is turned there is a keyway 44 in the periphery thereof in which engages the keys 45 extending into the openings in the sleeves 8|, 32

' On the inner end of the axle C that extends inwardly from the stand 13 there is the sectional bearing housing for the trunnion 26 of the warp beam. This bearing housing is formed of an upper semi-cylindrical section 46 and. a lower semi-cylindrical section 41. The lower section 41 is preferably formed integral with the inner end of the axle C. Extending laterally from one periphery of the lower section 41 are a pair of spaced apertured ears 48. Between these ears fit a lateral ear on the upper section 46 and this ear is indicated at 49. The apertures in the ears 48, 49 are in alignment and there is a hinge pin 58 extending therethrough. It will thus be seen that the upper bearing section 46 may be swung upwardly on the hinge pin 59 to facilitate the change and replacement of the warp beams.

When the upper section 46 and the lower section 4! are in the closed position as shown in Figures 1, 4, 5, and 6 there is a chamber 48inside the section 46 and a chamber 49 in the lower section 41. In the closed position these chambers form a continuous round recess which opens outwardly through the opening 50. The trunnion 26 on the warp beam extends through opening 58 into the chamber in the bearing housing. In the upper chamber 48 and at the end thereof are a pair of edgewise disposed segmental-shaped plates 55, 52 which form one half of the bearing cage. In chamber 49 in the lower bearing housing 41 are the end plates 53, 54 which form the lower half of the bearing cage. The plates 5!, 52 in the upper bearing housing 46 are secured to the housing and fixed thereto by means'of the screws 55. The screws 56 secure the plates 58, 54 in the lower section of the bear- These threads slide through the.

ing housing. At radially spaced points between the plates in each housing section are the antifriction rollers 57 the peripheries of which bear against the periphery of trunnion 26. Each roller 51 is supported in the same manner and referring to Figure 12 it is believed that a description of one will clearly teach the construction of the others. Between the plates 53, 54 there is an intermediate portion 88 0f the pin. At each 'end of the intermediate portion is a shoulder 59 which bears against the respective plates 53, 54. The rollers 57 rotate on this intermediate portion 58 of the pins. In each plate 53, 54 there is an opening 86 to receive a reduced shank 6| which extends laterally from the intermediate portion 58 of the pins. On the outside each plate has a countersunk opening 62 in which the reduced ends 6| on the pins are flattened or bradded as at 83.

V The axle C adjacent the bearing housing is formed with a bore 84 extending radially from which is a threaded opening to receive the set screw 65. The bore 64 registers with the inner ends of the registering chambers 48, 49 in which are seated the bearing sections. In the bore 64 is seated a cage 66 secured by set screw 65. The outer end of the cage is restricted by a flange 68 which prevents the three ball bearings 69 in the cage 86 from running out when changing the warp beams. The outer of the three ball bearings bears against the end of trunnion 26 and forms a thrust bearing to take upend thrust on the trunnion 26. The three ball bearings 69 contact one another.

On the outer face of the upper housing section 46 is formed a lug 1'8 in the upper portion of which is mounted a handle ll by means of which the upper bearing housing section is lifted upwardly when it is desired to change warp beam holders. A lower portion I2 of the lug overhangs the upper side of lower bearing housing section 4'! and this projecting portion is formed with a horizontal round opening 13. The outer face of lower bearing housing section 41 is formed with a boss 74 which has a threaded opening 15 to receive the threaded end of a spindle 16. The outer end of the spindle '16 has a fiat screw-head Tl. There is a hub '78 extending inwardly from the disk "wand the disk and hub are formed with a bore that embraces the spindle 16 while the head Tl bears on the outer face of the disk 19. Extending laterally from the periphery of the disk is an operating handle 80. A coil spring 8| embraces the hub 18 and has a prong 82 on its inner end that seats in an aperture in the boss 74. The outer end of coil spring 8i has a prong 83 that seats in an opening in the disk. The spring 8| normally holds the disk in the position where the latch pins, to be hereafter described, are retained in the locked relation. On the outer face of the lower bearing housing section 41 are spaced apertured ears 84, through which extend intermediate portions of the pair of latch bolts 98. The openings in the cars 83, 84 register with the openings 13 in the lug E2 on the upper bearing housing section 46. The outer ends of the latch pins extend outwardly of the ears 84, 85 and to the outer ends of these pins are respectively connected the rigid links 86, 81. The outer ends of the links are pivotally connected as at 88, 89, respectively, to pins on the diametrically opposite margins of the outer face of the disk. In the locked relation the inner ends of the latch bolts seat in the opposite ends of the opening 13 in the lug 72 and by turning the disk 19 counterclockwise as shown in Figure 4 of the drawings the latch bolts are released whereupon the upper bearing housing section may be opened. The inner or confronting ends of the latch pins incline inwardly and upwardly as at 9| so that they will be forced outwardly against the tension of spring 8| when the upper section 46 is swung from open to closed position. The lower end of the lug l2 striking against the inclined ends of the latch bolts forces them outwardly until they register with the opening 13 in which position they snap into the opening to lock the bearing housing sections together. The outer projecting ends of the latch bolts 90 are formed with a square shoulder 900. about which seats the square opening on the ends of the links 86, 81 and nuts are Secured to the links.

Having described our invention what we claim is:-

A bearing for the end of a shaft comprising a stationary support, an axle having an intermediate portion movable axially of and carried by the support, a sectional bearing housing mounted on one end of the axle and hinged one to the other, said housing having an opening remote from its mounting on the axle to receive the end of the shaft, roller bearings carried by each section adapted to surround the periphery of the shaft to provide radial support therefor, and a bearing element in the housing adapted to abut the end of the shaft to prevent axial thrust.
